Setting the principal

If the application has the custom authentication logic implemented, then we must set the principal in two places:

• Thread.CurrentPrincipal is the standard way to set the thread's principal in .NET.
• HttpContext.Current.User is specific to ASP.NET.

The following code shows setting up the principal:

private void SetPrincipal(IPrincipal principal)
{
    Thread.CurrentPrincipal = principal;
    if (HttpContext.Current != null)
    {
        HttpContext.Current.User = principal;
    }
}
